To vall whom it may concern: v v Be it known that I, Ovn M. NnLsoN, a citizen of the United States, residing at Montesano, in the county of Grays Harbor 6 and State of WVashington, have invented new and useful Improvements in Antiglare Devices, of which the following is a specification.

This inventionrelates to attachments for k the headlamps of vehicles whereby to remove or prevent the blinding glare ordinarily given out by headlamps and prohibited by' regulations in most localities.

An important object is the provision of a device of this character which is formed as an attachment which may be applied to an already 1 existing headlamp without necessitating any alterations therein and which will efiiciently operate to deflect downwardly all.

therays of light which normally pass from thelamp in an upwardlyinclined direction, the device throwing this light upon the roadway in advance of the vehicle and consequently preventin any blinding glare while improving the i lumination where it is needed.

An additional object is the provision of a device of this character which will be simple and inexpensive in manufacture, easy to install, positive in action, eflicient and durable in service and a general improvement in the art.

With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is an elevation of a headlamp showing my device applied thereto and in section,

Figure 2 is a front elevation and a Figure 3 is a cross section on the line 3--3 of Figure 1.

Referring more particularly to the drawings the letter A represents a headlamp of ordinary construction provided with the usual rim B. In carrying out my invention I provide a hood or casing which is here illustrated as having its upper portion curved as shown at 11 for conforming engagement upon the headlamp and having its lower portion rectangular as indicated at 12. This casing may be constructed of sheet metal or the like suitably painted, enameled or otherwise treated to present a pleasing appearanceand to prevent rusting when ex posed to the weather. Secured within the forward portion of this casing is a series of spaced parallel vanes or plates '13 which extend horizontally from side to side of the casing, while secured within the lower portion of this casing are forwardlyfand downwardly inclinedavanes or plates 14.

.In order to secure this casing upon the headlamp, I provide a band 15 which embraces the upper portion-of the lamp and which .mates with a plate member- 16 cut away along a curve as shown at 17 for embracing engagement upon the lower portion of the lamp. The band 15'and plate member 16 are connected by bolts 18 which pass through lugs 19, and 20 on the band and plate member respectively. The lower edge of the plate member 16 is. formed straight and hinged thereon,as shown at 21 is the bottom 22 of thecasing 10, it being preferable that a spring be provided 'at-thehinge for holding the bottom22 in its normal or horizontal position. v

In order that the upper portion of the easing may be secured with respect to the band,

I provide a bolt 23 which passes through the band and through a depending ear 24 on the rear edge of the top of the casing, nuts 25 being provided on the bolt for engaging against both sides of the car.

Assuming that the device has been installed as above described, it will be apparent that the light issuing from the lamp and tending to travel in an upwardly-inclined direction, will strike against the horizontal plates or vanes 13 and bereflected downwardly thereby so as to fall upon the roadway instead of glaring into the eyes of pedestrians or the drivers of approaching vehicles. As the plates 14 are inclined they do not in any way interfere with the light which passes from the lower portion of the lamp. In this way it will be seen that the light is really concentrated upon the roadway so that far better illumination is obtained than when the ordinary tin-protected headlight is used, while at the same time strict compliance with the police regulations of most localities is had.

While I have shown and described the preferred embodiment of the invention it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention I claim: I

1. An antiglare attachment for headlights comprising a plate member formed of detachably connected sections having semicircular cut out portions mating to define a circular opening for engagement upon a headlamp shell at the outstanding bead at the open front thereof whereby the bead will act to prevent forward displacement, and an open fronted casing hinged upon the lower edge of the bottom section and containing light my deflecting plates, and means for securing the casing to said lamp engaging plate at a point diametrically opposite the bin e.

2. An antig are attachment for headlights comprising a plate member formed of detachably connected sections having semi-circular cut out portions mating to define a circular opening for engagement upon a headlamp shell at the outstanding the open front thereof whereby the bead will act to prevent forward displacement, and an open fronted casing hinged upon the lower edge of the bottom section and containing light my deflecting plates, and means for securing the casing to said lamp engagin plate at a point diametrically oppgsite t e hinge, sald means comprising a lt passing through the lamp engaging ably bead at plate, an ear on the rear edge of the casing apertured for the passage of said bolt, an clamping nuts on the bolt engaging against the front and back of said ear.

3. A headlamp attachment comprising a casing adapted to beengaged'upon the orward portion of a headlamp and to extend forwardly therebeyond, plates within the casing for reflecting the light downwardly, and means for holding the casing on the headlamp consisting of a band encircling the upper portion of the lamp and detachconnected with the rear edge of the casing, and a plate member connected with the lower portion of the casing and cut away for embracing engagement u on the lower portion of the lamp and detac ably connect- 1 ed with said band.

4. An antiglare attachment for headlamps comprising a casing designed to be engaged upon the front portion of a headlamp, means for holding the casing in position, and a plurality of horizontally extending spaced parallel plates within the casing for reflecting downwardly rays of light emerging from the lamp in a normally upwardly inclined direction, and a plurality of u wardly and downwardly inclined plates wit in the lower portion of the casing, the lower portion of the casing and plate member being rectangular and hingedly connected.

In testimony whereof I afiix my signature.
